A great 1st step training tool for your dog up to 45-pounds. This 6-feet length stretches 8-feet. The resistance in the leash deters your dog from pulling. Great for your Medium to Small Dog such as a Sheltie, Cocker Spaniel, Beagle, etc. Let the leash comfort you and your dog as you have fun walking while the Bun-Gee Pup-EE stretches absorbing the shock of any pull.
